ActivePaper，board and pulps--Measurement of diffuse reflectance factor(Diff/Geometry)
纸、纸板和纸浆 漫反射因数的测定(漫射／垂直法)
Application Summary AI generated
This standard specifies the method for measuring the diffuse reflectance factor of paper, board, and pulps using a diffuse/vertical (d/0°) geometry. It is applied in the pulp and paper industry for quality control and product specification, particularly to determine optical properties like brightness and opacity. The test is conducted under standardized laboratory conditions using a reflectometer with an integrating sphere.
